替换现有xml文件的所有字符串？

Question

I'm trying to replace the existing .xml extension file's inside text with String. 我正在尝试将现有的.xml扩展文件的内部文本替换为String。

Why I'm doing this is: I wanted to read images from .xml file. 我这样做的原因是：我想从.xml文件读取图像。 But image did not loading file from the existing folder of .xml file. 但是图像没有从.xml文件的现有文件夹中加载文件。 I tried so many times to solve this problem. 我尝试了很多次来解决这个问题。 And only possible thing was the put the hard path of the Image file destination. 唯一可能的是放置Image文件目标的硬路径。 So then I started to try this: 因此，我开始尝试以下方法：

read the .xml file's inside string - Solved 读取.xml文件的内部字符串-已解决
get the full parent of the xml path - Solved 获取xml路径的完整父级-已解决
read text inside xml and export to string - Solved 在xml中读取文本并导出为字符串-已解决
find " <img src=' " existed area from string - Solved 从字符串中找到“ <img src=' ”存在的区域-已解决
put the Parent path after existed area - Solved 将父路径放在存在区域之后-已解决
save string to existing .xml by replacing all string - Unsolved? 通过替换所有字符串将字符串保存到现有.xml中-未解决？

Purpose of the work is "Show images from XML file". 工作的目的是“显示XML文件中的图像”。 So please someone answer unsolved article. 因此，请有人回答未解决的文章。 And don't suggest me about methods like Base64ToImage. 也不要建议我使用Base64ToImage之类的方法。 I just want to go like this way. 我只想这样走。 Hope I will have my answer here. 希望我能在这里得到答案。

I'd use XDocument and HTMLAgilityPack 我会使用XDocument和HTMLAgilityPack

var xml =
@"<base>
    <child><![CDATA[<img src=""/path"" />]]></child>
</base>";

var xDocument = XDocument.Parse(xml);

var xChild = xDocument.Descendants("child").First();

var cData = xChild.Nodes().OfType<XCData>().First();

var htmlDocument = new HtmlDocument();

htmlDocument.LoadHtml(cData.Value);

var imgNode = htmlDocument.DocumentNode.SelectSingleNode("img");

imgNode.Attributes["src"].Value = "/new/path";

using (var writer = new StringWriter())
{
    htmlDocument.Save(writer);
    cData.Value = writer.ToString();
}

xDocument now contains: xDocument现在包含：

<base>
  <child><![CDATA[<img src="/new/path">]]></child>
</base>
